Instinct Solar Tactical Battery Dies Immediately

I've had my instinct solar tactical for ~ x2 years and have loved the watch. I use it for everyday wear and to track my runs. Recently over the last x3 months, when I switch the watch over into GPS mode it will connect to GPS, but then when I hit the button to start/record the run the watch immediately dies. After it dies I can't turn it back on until I recharge it. I've experimented with everything I can think of. It dies even if battery is 100% and won't turn back on. I've updated the software to the most recent (Currently 19.01). I've tried to hard reset it. Nothing seems to work. Guessing I should have it repaired but didn't know if there were any thoughts on this.
